Abstract
One of the main goals and objectives of breeders in modern sheep breeding is the preservation and improvement of the genetic potential of animals. In this regard, the determination of erythrocyte antigens will help to identify errors in accounting for origin, determine the economic and useful qualities of animals in the early stages, as well as evaluate breeding sheep based on the quality of their offspring, and select the best compatibility of parental pairs. The results of the study showed that allelic polymorphism of blood group factors indicates both similarities and differences. The maximum number of variants of parental pairs was in the range of 0.31-0.60 and amounted to: parents — 118 pairs (79%), and when selecting parental pairs with this index, lambs with the highest live weight can be obtained. . Indicators of the economic efficiency of raising lambs, pairs of rams and mats, obtained from different selections, show that the greatest profit for the farm was brought by animals with an IAS of 0.31-0.60.
